Our Official Certificate of Origin Policy is available here Why are the values for percentage purity as determined by Titration sometimes greater than 100% , on the Certificate of Analysis ?
• Titration measures the ions present in reference to a standard. If other ions (of similar valency) are present in the solution then these may contribute to the value recorded, in addition to the contribution made by the standard itself. The value recorded is greater than that of the standard alone as a result of the titration not being able to differentiate between ions.
